This is a stainless steel thermal flask "Shuttle Joy HSD-1000" made by Nippon Sanso, which is no longer sold. - Brand: Nippon Sanso Corporation - Model: HSD-1000 - Color: Green - Capacity: 1.00L My parents ran a hardware store, but it closed over 30 years ago. This is a dead stock item that was sold at that time. It is an unused item that has been stored in a warehouse for many years, but the outer box has dirt and damage due to aging. We cannot guarantee the heat retention and cold retention performance. It will be sold as is. How about it for those who like Showa retro goods and items from that time? Please make your purchase based on the images. #NISSAN #VACUUMBOTTLE #VacuumBottle
